The short version

  • Only Go has a free tier, so it costs nothing to try first.
  • Each has a real cost: Anthropic API pricing varies significantly by model tier; Go no built-in generic types until recent versions, requiring workarounds for type-safe collections
  • They diverge on capability: Anthropic API covers Multiple models, Go covers Goroutines.

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Anthropic API

  • Pricing varies significantly by model tier
  • Batch processing and Fast Mode add additional surcharges
  • US-only inference costs 1.1x standard pricing

Go

  • No built-in generic types until recent versions, requiring workarounds for type-safe collections
  • Error handling through explicit return values considered verbose compared to exception-based approaches
  • Smaller standard library compared to Python or Java; requires external packages for common tasks
  • Package management can create version conflicts and dependency hell issues
